Ma Shi Chau
Ma Shi Chau (, literally "Horse Dung Island") is an island of Hong Kong, under the administration of Tai Po District. It is located in Tolo Harbour in the northeast New Territories (near Sam Mun Tsai). It is connected with another island, Yim Tin Tsai, by a tombolo traversable at low tide. Geography Ma Shi Chau has an area of 0.61 km2. It is part of the Ma Shi Chau Special Area, as it exhibits tombolo and tide features rarely seen in Hong Kong. It is the largest island of the four in the Special Area, the others being Yeung Chau, Centre Island and an unnamed island near Yim Tin Tsai. It has sedimentary rock dating back to the Permian period that is protected by its Special Area status.

Hong Kong UNESCO Global Geopark
Hong Kong UNESCO Global Geopark (), formerly Hong Kong National Geopark (香港國家地質公園), was inaugurated on 3 November 2009. It is a single entity of land area over 150 km2 across parts of the eastern and northeastern New Territories. On 18 September 2011, UNESCO listed the geopark as part of its Global Geoparks Network. The Hong Kong UNESCO Global Geopark consists of two geological regions: * the Sai Kung Volcanic Rock Region, with its widely distributed tuff volcanic rocks displaying prismatic columnar jointing, which are of international geological significance * the Northeast New Territories Sedimentary Rock Region, which comprises sedimentary rocks formed in different geologic periods, showcasing the complete geological history of Hong Kong. History In 2008, the Hong Kong government commissioned a study to investigate the feasibility of establishing a geopark. The study identified two suitable regions, namely the north-eastern New Territories and Sai Kung. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravity, gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the #Phase and amplitude, phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see ''#Timing, Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal cycle, diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tidal Islands
A tidal island is a piece of land that is connected to the mainland by a natural or man-made causeway that is exposed at low tide and submerged at high tide. Because of the mystique surrounding tidal islands, many of them have been sites of religious worship, such as Mont-Saint-Michel with its Benedictine Abbey. Tidal islands are also commonly the sites of fortresses because of their natural fortifications.

Uninhabited Islands Of Hong Kong
The list of uninhabited regions includes a number of places around the globe. The list changes year over year as human beings migrate into formerly uninhabited regions, or migrate out of formerly inhabited regions.

Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centre Island, Hong Kong
Centre Island or A Chau () is a small uninhabited island of Hong Kong located in Tolo Harbour, in the northwestern part of the territory. Administratively, it is part of Tai Po District. Geography The island has an area of 0.035 km2. Its highest point is at 26.8 m. The island has a partially rugged coastline with sections with sandy beaches. The interior of the island is covered by trees. History A mid-Neolithic prehistoric site dating back to about 6,000 years ago has been identified on Centre Island during a survey conducted in 1997–1998. Prehistoric sites have been discovered on two other islands of Tolo Harbour, namely Yuen Chau Tsai (3,000 years, Bronze Age) and Yim Tin Tsai (4,000 years, late Neolithic). Conservation Centre Island was designated a Site of Special Scientific Interest in 1982. The designation is based on the geological interest of the island. Centre Island is part of the Ma Shi Chau Special Area, together with three other islands in Tolo Harbour, n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tombolo
A tombolo is a sandy or shingle isthmus. A tombolo, from the Italian ', meaning 'pillow' or 'cushion', and sometimes translated incorrectly as ''ayre'' (an ayre is a shingle beach of any kind), is a deposition landform by which an island becomes attached to the mainland by a narrow piece of land such as a spit or bar. Once attached, the island is then known as a tied island. Several islands tied together by bars which rise above the water level are called a tombolo cluster. Two or more tombolos may form an enclosure (called a lagoon) that can eventually fill with sediment. Formation The shoreline moves toward the island (or detached breakwater) due to accretion of sand in the lee of the island, where wave energy and longshore drift are reduced and therefore deposition of sand occurs. Wave diffraction and refraction True tombolos are formed by wave refraction and diffraction. As waves near an island, they are slowed by the shallow water surrounding it. These waves th ...
